Based on high temperature and pressure (maximum pressure of 30000psi) and hydrogen sulfidecontaining characteristic of oil/gas well, FST developed high-pressure hydrogen sulfide-containing wellhead safety control panel.

Controlled objects of high-pressure hydrogen sulfide-containing wellhead safety control panel are subsurface safety valve, surface main valve and surface wing valve. In addition, it has the functions of remote shutdown, local shutdown, ESD station shutdown, automatic emergency shutdown of fusible plug during fire, and automatic shutdown when flow line pressure is too high or too low, etc.

High-pressure hydrogen sulfide-containing wellhead control panel mainly uses pneumatic hydraulic type; communications and security control systems are executed by RTU and SCADA integration, which allows local and remote operation control . This type of wellhead control panel is suitable for NACE application environment of H S, CO , and the use of valves and fittings made of 316L or Inconel 2 2 materials can also be provided on request.

RTU control system uses redundant CPU and all channels configure surge protector. The access system of all kinds of field instrument data (well pressure, casing pressure, temperature, throttle valve opening) can control various types of field equipment according to the requirements. The cabinet is equipped with explosion-proof screen, and is provided with perfect operation control software to setup parameters easily and execute automatic control.
